Unity looses mouse click handler when using enabling USB headset

[Jevonearth]

I have a Plantronics D100 headset.

When I press the button on the headset to enable it, Unity looses its click handler, in that it can not click and drag windows.

The cursor is visible and moves just fine. I can switch applications using Alt+Tab, and I can launch new applications using the keyboard. But I cannot close the existing window, or change focus to another window by using the mouse.

The Headset microphone and speaker work just fine!

Tested this on a laptop and desktop machine. Both running Ubuntu 12.04.

The headset I'm using is a Plantronics D100 unit.

I have had this problem for the past month while on the 12.04 beta release.

Status changed to 'Confirmed' because the bug affects multiple users.

[Jeff Rasmussen (jeffrasmussen)]

I'm having the same type of issue. It seems to pop up when there is a unity issue like when I have the auto-hide turned on for the Nav bar and I try to switch desktops or when I tried to move a Chrome tab out of the current window into its own window.

My mouse buttons are not usable until I log out and back on. When I tried moving the Chrome tab, the window followed my mouse like the button was still depressed and no combination of keyboard or mouse buttons were able to break the 'stuckness'. When I tried to switch desktops I got stuck seeing 4 desktops with content on each one but I was not able to click into a desktop.

[Jevonearth (ebjorsell)]

I have had some progress with this issue. Either something in my system has changed (I got a batch of updates this morning) or I have just explored the behaviour more thoroughly.

When I make the headset by pressing the button on the side, it turns the audio channels on. I can see this even in /sys/kernel/debug/usb/usbmon/0u as follows:

Turn headset ON:
ffff88012c4d6f00 1619795766 C Ii:3:002:3 0:2 5 = 04200413 08
ffff88012c4d6f00 1619795950 S Ii:3:002:3 -115:2 64 <
Turn headset OFF:
ffff88012c4d6f00 1623377775 C Ii:3:002:3 0:2 5 = 04200452 08
ffff88012c4d6f00 1623377969 S Ii:3:002:3 -115:2 64 <

If I loose the click handler when the headset is active, it comes back when I turn the headset off. I think this is new behaviour, but I can't be sure if it was just that I did not notice this previously.

When the click handler is lost, I can still see the click events show up in: /sys/kernel/debug/usb/usbmon/0u
Mouse button Down:
ffff88012c9b4600 1817445838 C Ii:4:002:3 0:2 15 = 20010201 00000000 00000000 000000
ffff88012c9b4600 1817445948 S Ii:4:002:3 -115:2 32 <
Mouse button Up:
ffff88012c9b4600 1818011837 C Ii:4:002:3 0:2 15 = 20010200 00000000 00000000 000000
ffff88012c9b4600 1818011944 S Ii:4:002:3 -115:2 32 <

But the clicks don't seem to be picked up by the window manager.

Another odd thing I noticed is that the problem does not happen if I turn the headset on while my cursor is hovered over the desktop background.
If the mouse cursor is hovered over my terminal window, and it is displaying the I-Beam Pointer instead of the regular pointer, then I loose the click handler.

That's all I have for now. If anyone wants me to try more tests or gather more information, please give me some instructions.

Thank you.

[SirPecanGum (sirpecangum)]

I am having this bug too but I don't use a Plantronics D100 headset. Loss of mouse functionality other than movement of cursor. Alt+tab also stops working intermittently. The rest of the keyboard seems functional. Logging out and back in seems to temporarily fix the problems.

[SirPecanGum (sirpecangum)]

Could this be similar to:

Bug #41301
Bug #878859

[SirPecanGum (sirpecangum)]

I have just updated, rebooted to complete and then logged straight in to this problem. It is as if unity/the desktop will not give up focus to newly opened apps. alt+tab does not work. Gnome Classic is also effected.

[Jevonearth (ebjorsell)]

I retested this issue today and it still exists. However, I also tested this in other window managers, such as LXDE, Openbox and Gnome/Openbox.

I get similar behaviour in all window managers, so it appears that this issue is not specific to Unity at all.

I'm asking for guidance from the community on where to file this bug, and/or how to get more useful information.

Thanks.

[amias (amias)]

I can confirm this bug with two different plantronics usb headsets a blackwire c-620m and a blackwire c-420m.

pressing the volume buttons triggers a lack of mouse clickability and unplugging the headset restores mouse functions.

this is on a fully updated precise install.

also this bug is marked as a duplicate of #1007525 but that bug referers to a different hardware however the problem is the same , bad input device handling is somehow making the volume buttons block mouse clicks.

[Jerry Wooten (woo10jw)]

Sorry if I'm not supposed to post here, just thought my circumstance might help.

12.04 fresh install with Cinnamon, Unity and Gnome desktop, it happens on all desktops.
I have a usb creative fatality headset and microsoft usb trackball mouse. I haven't notice any particular time the problem happens, my headset is always pluged in. Left click, right click stop working all together, have to Ctrl-Alt-T then sudo reboot, sometimes 2 or 3 times to get mouse to start working. Will keep headset unplug to see if this changes anything.

[Jevonearth (ebjorsell)]

I updated this bug so that it is no longer marked as a duplicate of #1007575 as that issue concerns a different make & model of device, though same class of device, and as far as I can see, identical issue.

Here's hoping we get some developer love on this issue.

[Jevonearth (ebjorsell)]

I have reproduced the same problem in 12.10.

[Chris J Arges (arges)]

As a workaround you could use something like this to add a quirk ignore the buttons:

sudo rmmod usbhid && sudo modprobe usbhid quirks=<lsusb id>:0x04

where lsusb id is the output of lsusb that corresponds to your device:
such as 0x041e:0x0403

Please update if this helps along with the lsusb ID of your device.

Thanks

[Gabriel Pereira Borges (gpborges)]

I am also being affected by this bug using a Plantronics 655. This is VERY anoying and didn't happened in 10.04 :-S

dmesg:

[Gabriel Pereira Borges (gpborges)]

And yes, the workaround posted in comment #14 fix the issue. I've put it in a shell script and execute it when I plug the headset. We can also create a udev rule to execute the script right after plugging in the headset, right? :-)

And do you know if this is fixed in newer releases? (12.10)

Thx!

[Jevonearth (ebjorsell)]

The workaround in #14 is also working for me. However, whenever I pick up the device, or press any button on the device, I need to reload the usbhid module, which is very annoying.

I looked into using udev rules as suggested in #16, but the events seem to be limited to USB device attachment/detachment. I don't know how to find the event associated with the events associated with me pressing buttons on the headset.

The 'udevadm monitor' command does not list any events for button presses, just for USB attach/detach.

FYI, here's the command I use, as you can see I also unload/reload hid_logitech_dj, as I can't unload usbhid otherwise.

 sudo rmmod hid_logitech_dj && sudo rmmod usbhid && sudo modprobe usbhid quirks=047f:ab01:0x04 && sudo modprobe hid_logitech_dj

Looking forward to finding a workable solution to this. Sure is nice to use my headset again, despite having to reset quirks mode every-time I start/finish a call.

[Jevonearth (ebjorsell)]

@gpborges This issue has not been fixed in 12.10.

I have a Plantronics savi 750-ish headset which plugs in USB and shows up as a USB audio device. However, when I lift the headset off of the cradle, my mouse and gnome starting acting 'fishy'. Some things the left mouse button works, some things they don't. alt+f2 doesn't work. windows hotkey doesn't work. cannot change between programs by clicking other windows. Sometimes I can click between tabs. sometimes I can highlight text on the focus window, but certainly no highlighting of text on other windows. etc. Just fishy. Disconnecting the headset from USB resolves the problem. Below you will find the xorg log and the dmesg log of connecting, breaking, and disconnecting the device.

whoah. this headset actually pretends to be a mouse?

connect the headset, then run evemu-device and evemu-record against the /dev/input/eventX device file while reproducing the above issue and attach it here please.

[Eric (eric-redhat-bugs)]

so I got nothing... looking in the Xorg.0.log I get:

so I ran:

I was simultaneously running:

# evemu-device /dev/input/event16

Which gave one line and exited:

so you can see that it presses both middle and side button (buttons 2 and 8 in X) and doesn't release them (presumably it does when you put it back?). That's
why the button is stuck and things break.

when you disconnect the device X releases all buttons held by that devices, so that's why normal functionality comes back.

not much we can do here, best thing is to tell X to ignore this device:

Has anybody made any progress on this issue please?

[Dave Chiluk (chiluk)]

A similar issue was resolved for a Creative Labs headset in https://pad.lv/1007575 with kernel 3.5.0-24.37 which has been released.

If you are running a kernel later than that and this is still occurring please say so in a comment.

Well apparently pad.lv doesn't like https. Here's the direct link to that other bug https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1007575

[Jevonearth (ebjorsell)]

The fix for 1007575/SB Arena USB headset doesn't work for this bug which is related to a Plantronics headset.

I believe the vendor codes are different, but the actual fix may be the same.

I tested this on Kernel 3.7 and the bug was still present. I'm running Kernel 3.8 right now, but not in a position to verify this until later in the week. I'm 95% sure it has not been fixed in Kernel 3.8.3-2

-Jev

[Jevonearth (ebjorsell)]

I actually got time to quickly test it, and yes, this bug still affects Plantronic headsets on Kernel 3.8.3-2

This command;
sudo rmmod usbhid && sudo modprobe usbhid quirks=047f:ab01:0x04

will resolve the issue, but you need to run it every time the device changes state, so it's not a very practical solution.

[Jacques Burger (jacques-burger)]

Thanks Jevonearth, was just about to test the newer kernel, now I don't have to.

Could a guru script something up that can detect state change and run that command as needed?

That way we can use the Plantronics at least a little for now until a permanent fix is available.

[Jacques Burger (jacques-burger)]

Turns out this is a XORG issue.

Fixed it by creating a file called "50-plantronics.conf" in "/usr/share/X11/xorg.conf.d" with the following content:

Section "InputClass"
        Identifier "Plantronics"
        MatchVendor "Plantronics"
        Option "Ignore" "true"
EndSection

This gets X to ignore the Plantronics device, which makes the mouse problem go away.

Unfortunatly this also seem to stop the MIC from working so I need to figure ouy how to get that better.

Hopefully somebody makes more progress and has some more advice soon.

[Dave Chiluk (chiluk)]

As I don't have this headset, and it appears to be a different issue altogether there's not much I can do to help on this one.

[Mike Butash (michael-butash)]

I'd spent the weekend dealing with this as last week someone at work gave me one of these plantronics devices to use, and I was stoked it would act as a headset for my pc as well. Then I started getting the screen freeze issue, and never figured out it was linked to the stupid headset. After upgrading from 12.04 to 13.10 (hitting a ton of ubuntu bugs along with the way with the intel 4000 video chipset, forcing me to hit 13.10 until I got a stable system again), and trying every window manager out there, still had this issue... Seemingly after doing anything that triggered the sound device, finally figured out it was related when disconnecting the plantronics headset would allow me to click on my display windows again. Argh!

If nothing else, can you (Canonical) simply blacklist the device by default, or at least add the xorg entry if you can't find a better way of dealing with it? This is likely to make any user lose their hair as it about did for me.

Jevonearth, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

Please note, given that the information from the prior release is already available, doing this on a release prior to the development one would not be helpful.

RMB, MMB, scroll, and pointer location all function across touchpad, USB mouse, and graphical tablet, but LMB does not. Running the 3.13.0-23-generic kernel.

The workaround
sudo rmmod usbhid && sudo modprobe usbhid quirks=<lsusb id>:0x04
does not work, instead all clicking functionality is lost when the headphones are plugged in.

Reported as bug #1307044

I have a very similar-sounding issue with Logitech wireless mouse (no headset). Periodically loses click handlers or something with very closely related symptoms. Try switching to console and back (Ctrl-Alt-F1, Ctrl-Alt-F7).

Christopher, I created bug 1371853 and added you there.

[Christian Löpke (innos-zorn-chris)]

I can confirm this bug with a Corsair VOID RGB wireless headset.
Mouse movement works all the time but sometimes (every 15 min ca.) mouse clicks are not recognized any more till I switch tty with strg+alt+F1 and back to seven.

Im using XUbuntu 15.04 and really want to help.
But I dont know where to look for debug outputs.

Can someone help me ?
Which informations are required to debug this ?

[penalvch (penalvch)]

Status changed to 'Confirmed' because the bug affects multiple users.

OR using EOL release, no debug logs, and no response for years.
